Mouse Models of Cancer Study

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

The Retinoblastoma Gene

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Area of Science:

Computational biology
Genomics
Oncology

Background:

Intraoperative molecular diagnosis of brain tumors is crucial but challenging due to time constraints.
Existing machine learning methods are too slow for real-time clinical applications.

Purpose of the Study:

To develop a computationally efficient framework for live cancer epigenome classification.
To enable rapid molecular diagnosis of brain tumors during surgery.

Main Methods:

Developed MethyLYZR, a naive Bayesian framework for epigenome classification.
Utilized nanopore sequencing to analyze over 200 brain tumor samples.
Evaluated performance in a clinical setting with intraoperative sequencing.

Main Results:

MethyLYZR achieved highly accurate brain tumor classification within 15 minutes of sequencing.
The framework runs in parallel with minimal computational overhead.
Demonstrated potential for live classification in clinical neurosurgery.

Conclusions:

MethyLYZR offers a viable solution for rapid intraoperative molecular diagnosis of nervous system malignancies.
The technology shows promise for broader oncologic applications and liquid biopsy analysis.
Further prospective studies are needed to confirm clinical utility.
